Pest Control in Govans, Baltimore

Why do older Govans houses get carpenter ants and wasps?

Wood porches, window frames, attic eaves and old roof edges are the places where moisture and shelter meet on a Victorian or Craftsman house. Carpenter ants favour wood that has been damp, and they nest in it, so a leaking gutter or a porch post that stays wet can set up a colony. Paper wasps and yellowjackets build in eaves, porch ceilings and wall voids, and their nests tend to be at their largest in late summer.

If you see large black ants indoors in spring, sawdust-like frass under a window or a rustling sound in a wall, call before you spray. Spraying scatters foraging ants and can make the trail harder to follow. A technician traces the trail to the nest, then treats the nest and the conditions that created it. See carpenter ant control and wasp and hornet nest removal for the process.

If you are not sure which pest you have, take a clear photo and note where and when you saw it. Carpenter ants are most active at night and in spring, while wasps are most visible on warm days in late summer. Those details help a technician decide what to bring and where to look first, and they save a visit's worth of guesswork.

What about squirrels and raccoons in Govans attics and chimneys?

Mature trees beside roofs give squirrels a ladder to the eaves, and old roofs, soffits and chimney openings can offer a way in. Raccoons also use chimneys and attics, especially in cold weather or when raising young. Scratching at dawn or dusk, thumping at night and a musty smell in a closet are the usual signs.

Do not seal an opening until a technician has checked whether animals are inside, since trapping a mother in an attic can leave young behind. Removal is followed by repairs and screening so the opening is closed for good. Our squirrel and raccoon removal page covers the steps. Trimming branches back from the roof is a simple measure that makes a real difference.

Streetcar-era houses often have deep eaves and attic spaces that were built for ventilation, and those same openings can let in squirrels, wasps and bats. Screening vents with sturdy mesh is a common fix, though the right material depends on the opening, and a technician will explain what the house needs.

How do mice and rats use the rowhouse blocks near York Road?

The traditional rowhomes in Winston-Govans share party walls, and the alleys behind the York Road shops carry trash from shops and houses alike. Norway rats tend to follow food and cover, so a dumpster pad or an overfilled bin can bring them to the back of a block. Mice may use the connecting gaps inside the walls.

A technician inspects the alley side and the cellar, seals gaps and sets bait or traps where activity is found. Because the houses are attached, it helps to talk to the neighbours. See rat control and mouse control for what a visit includes. Rowhouse sealing is covered on our rowhouse pest proofing page.

On the commercial side, York Road shops and restaurants face the same alley issues as the houses behind them. A shared dumpster is only as secure as its least careful user, so owners often benefit from agreeing on lid and pickup routines with neighbours. A technician can point out where the alley's weak spots are.

Is a termite inspection worth it on an older detached house?

Eastern subterranean termites can work through old wood and damp framing, and a house with a stone or brick foundation, wood sills and a porch has plenty of places where wood meets soil or moisture. Not every older house has them, and the only way to know is to have it looked at. Swarmers in spring, hollow-sounding wood or mud tubes on a foundation are signs to act on.

If you are buying in Govans, a wood-destroying insect check is often part of the sale. Our termite inspection page explains what a technician looks for, and termite control covers treatment options if activity is found.
